In the drawings, designatesa metal tube which is formed preferably by bending sheet metal into cylindrical form, and by holding the abutting ends together by Aany suitable means as by lan interlocking joint (not shown). The tube 2O is closed at one end by a lock barrel or plug 21, ina manner to be longitudinally movable therein. Removal i of the plug 21 from the case 20 is prevented by means of a screw pin or set screw 22 driven into the plug 21, and having the head thereof lconfined within the elongated slot 23 of the tube` 20. The other end of the tube 20 receives the cylindrical portion 25a of a nonconducting terminal block 25, and is provided `with oppositely disposed notches or bifurcations 24 for receiving terminal supporting portions 255 which bear against the portions 26 of the tube`20 which defines theend of .the notches 24. y i

The block 25 insulatingly supports switch contacts 32 which aresecured by terminal bushings 33, each receiving a terminal screw 34. As shown in Figs. 1 and 6,'eachcontact plate32 iit-s within a recess 38 inthe block 25having parallel sides so that the plate 32 cannot turnwhile located within the recess 38. The` terminal bushing 33 passes through the contact 32, and is provided with a headed member 33a and is held in engagement with the plate 32 as shownin Fig. 1, by riveting over a portion of it as indicated by the numeral .39,against a washer located on the outside of the block 25. bushing 33 from turning screw 34 is turned. i

rlhe contacts 32 are engageable by. aY resilient ring contact or bridging member 41, insulatingly supported by a non-conducting block or Contact carrier 42 which is slidable within the inner end of the tube 20. l

The carrier 42 is somewhat cup-shaped in formation,

when the terminal spring receptacle 43, the hub 44, and the guide lugs 45, which latter are slidably received within the bifurcations 24 of the case 20.

Within the body of the carrier 42, are an-v being moulded from insulating Y materialto provide the cup-.shaped recess or This prevents the j chored the tubular headed inserts 46 which providea retaining means for the ring contact 41, by the shank portion thereof being received by apertured or notched ears 51 of the ring, and the tubular portions of the protruding inserts being turned over to secure the Contact plate 41 against the carrier 42. The spring contact ring' 41 is forced. out of the planar alignment thatit would naturally assume into that form inV which the Web portions 50 between the attaching ears 51, are angularly disposed With respect toa common plane, as shown in Fig. 1, and when assembled with its carrier 421Within the case in proper relation with the fixed contact carrier 25, Will'provide for `resilient and Wiping engagement with the fixed contacts 32, as will hereinafter appear. Centrally of the 4block 42 and 'extending longitudinally thereof, is a bore 47, terminating in a countersinlr' y 48 vcentrally of the hub 44.

` rlhe c'ount'ersinl 48' provides for the Vseating engagement of a contact actuating mem- Vber, lwhich comprises a short tube 52 cennected at one end with a cup-shaped member 53 and having one end thereof rolled inwardly as at 54 to provide a seatingmember to eooperate with the coun'tersinlr 44. Inthe present instance the tube 52 and cup 53V are con-V nected by providing an annular ridge 5o near the opposite end ofthe'tube to provide a seat for 4the edge of a'centralopeningin thebot` tom of the cupmember, and spinning "over the' protruding end ofthe tube 52( against 'the bottom o'f the cup as at 56, after the cup has been placed on the tube against the ridge or shoulder. The contactcarrier 42 With its associated actuating 'member 'are 'contained 'Within the case 2O withV the 'tube 52 passing through thecentralaperture 57 of the block 25, and vWith the'cup memberv '53' disposed "betw'eenthe inner Vend of the plug 21 and the terminal block so that 'positive 'driving tional Contact between the pin and the case 20. The contact actuator and the controller plug are assembled as a unit, by inserting the cup 53 Within the recess 64 so that thel apertures 61 and 65 are in alignment and then insertingl the pin 62 therethrough until thefconnte'r bored end ofthe pincan beeX- Akpanded as shown in Fig. 1. Between the bloclr 25 and the cup member 52 there is placed a 'compression springt?) Which-'normall'yurgesthe cup and plug members to an extended position, allowing the contacts 32 to be bridged by the resilient member 41.

The inner end ofthe tube 20, beyond the bloclr 25, is provided With a reinforcing col- 'lar 7G,permanently-fixed thereto as by spot Welding, whichY preventsf the removal ofthe "fixedcontact carrier y 25 *fromV the' `bifurcated orl notched lend of; the' tubularl case 2O,l and provi es rafhousingfand protecting inclosure for 'tlie\switcli contactsA hereinbefore described.

This positive "drive is- 'assured' by"provi`ding the" cylindrical Wall of the cup 53 at substanvti'ally diametric points with apertures 61 for 'receiving anelongated headed pin 62provided with a vcounter bored stem as at 63. The cup member 53 is somewhat smallerin diameter than the bore of the case '20, and

is 'providedi with fa key cylinder? 8O operable- Iintheusualrinanner towithdraw a'spring pressed bolt 31 from an .aperture 32 in the Consequently Smaller than the Cross Section adyacent.-casi ng or tube 20, upon the inseryof the controller plug 21.v rlfhe inner end of Vthev member 21 is therefore providedwith a longitudinal bore or recess 64, into which tits the cup 53. The Wall of the bore so formed is provided with the lateral openings 65,.

Which when assembled Withthe cup 52-Within the recess 64 will be in alignment with the. apertures 61 in the Wall of the cup, and Will be of such'dimension as to freely receivef'fthe enlarged-ends of the pin 62 when assembled Within 'the f casel 20, and" prevent any1y fric# f' 85; to a circuit open*positiom'which isthat positionillustrated in- F ig. 5,-Without theuse llof thelre'y'y S35, sincethe bolt 81 rides freely over thep'ortion 85 of vthecase 20- when the against the inner surface of the tubev 20 as at plug 21 ismanuallydepressedoraforced in1 130 wardly to the position as illustrated in Fig. 1. The reverse movement of the plug 21 cannot be accomplished, however, without the use of the proper key 83. v i v Movement ofthe lock barrel v21 from the circuit closed position to the circuit open positionor the position illustrated in Fig. 1, will move the contact carrier 42 with theV cupmember 53 inwardly therewith, against thek mountable connection between the control unit, and a remotely positioned boltingunit. The endwise movement of the plug 21, with the a-ssociated cup 53 and contact carrier 42, is used in this instance to control a member which will prevent operation of the transmission mechanism to connect the engine with the driving axle of the vehicle as appears from the description that follows:

The transmission gear shift mechanism is not shown herein, but it will be understood to be enclosed in a case, the presence of which is shown at 90 of Fig. 1, and toinclude a pair of plates or rods 91 and 92 slidably supported by the case 90 and movable whenthe gear shift lever is used to connect the engine with the vehicle propeller shaft, in any one of its several selective gears. 1t will be further understood that vvhen the .gear shift lever is in the neutral position, that members 91 and 92 will be located-so that notches 93 and 94 provided respectively by the members will be located directly adjacent 'to each other so as to receive a ball 95 which is guided by an opening 96 has communication with av f bore 97 extending substantially at right an- -45 gles t-o the direction of .movement ofthe members 91 and 92 and provides a retracting recess for the ball 95.

The bore 97 is enlarged at the outer end as at 9S and is designed to receive a reduced portion 99 of a sleeve member 100.y The sleeve l100 constitutes a conduit sup-port and a guide for a spring pressed locking bolt 101.

The locking bolt 101 is slidable within .the

sleeve 100 and cooperates with the reduced portion of the bore 97, when operated by the control unit described above, to force the ball 95 into the aperture provided by the notches within the enlarged portion 98 ofthe bore 97,

and fixed therein by a pin 102 driven through a portion of the case l90 into an annular y groove `103of the `*reduced portion 99 of the sleeve. f

The control unit and the boltingunit hereinabove described are operatively and nondemountably connected by an armored protective means as follows: 'y

The operative control betweenthese units comprises a Bowden wire 110 passing through f ra sleeve 111 seated within the tube 52 adjacent the cup 53 and is providedwith a flange 112 disposed within the cup 53 at the innerV end of the plug 21. The end of the Bowden wire 110 i's bentinto arloop or lateral extension as at 113 to prevent removal or withdrawal of the wire from the sleeve 111 just described. The sleeve and Bowden wire may be'secured together in any suitable manner as by soldering, indicated generally at 114.

. vThis-Bowden wire 110 extends through the tube 52 and the sleeve portions or conduit supports 71 and 100, and is permanentlyfixed at the other end to thevlocking bolt 101 in Vany desired manner. c In the present instance the Wire 110 is inserted ina longitudinal bore 115 of the bolt 101 and is retained therein by a pin 116 driven through a trans- :verse hole inthe bolt 101, to `form a loop 117 vand .force it vinto a second lateral recess 118 adjacent 'a he longitudinal'recess 115.r The Bowden`- wire is encased by a Bowdenwirel tube 120 which passes through the central apertures of the conduit supports 71 and 100 and which are fixed thereto in the following manner: The sleeve 71 is counterbored as at 7 6 provi-ding a recess for the flaring end or expanded edge 77 of the Bowden wire tube 120 as clearly shown in Fig. 1. Against the end of theBoWden wiretube thus expanded and within the countersink 76 is placed a washer, 78, which is retained therein in any preferred' manner as by staking.v The other end of the Bowden wire tube is liXed to `the' sleeve in a similar manner.

The Bowden wire controlis non-demountably and indestructibly protected against rupture, or tampering with, by an inner cable 121 surrounded by an outer armored conduit 122. One endof the armor 122 is received in anl enlarged bore 123 of the sleevey 71 and is permanentlyv retained therein as by swedging the sleeve portionabout the end ofthe armor as indicated at 124. The other Y end of the armor 122 is'received within a.

similar recess 125 of the sleeve 100 and is permanently retained thereinas by` swedging, asvshown at 126. One or `more supporting Yclips 127 may be provided to support the venient form Vof structure therebetween, thus preventing possibility ofstretching the con-v trol-unit suiiiciently to withdraw fthe bolt 30 101 from its control locking position.
